## Computing basics

---

## File/directory awareness
+ Every computer has a file/directory system
+ There's a default or home folder
   
   ```r
   ## use this to see your home folder
   normalizePath("~")
   #> [1] "/Users/kearneymw"
   ```
+ Files are organized like a tree
   - You can move from one branch to another
   - Moving from one folder to another is linear
+ Bash shortcuts
   - Use `..` to go back a folder or `../..` to go back two folders
   - Use `~/` as a shortcut for home

## Don't fall asleep yet!
Why do you need to know about your computer's file directory system?

+ Because you need to know where things are to interact with them!
+ Because you want to be able to replicate your work!

> **tl;dr**: open your file browser. See how they're organized? Yeah? Good!

---

## Don't let these terms confuse you
+ `File` is the **name**/location of a file
+ `Path` is the name/**location** of a file
+ `Folder` is the **name**/location of a file folder
+ `Directory` is the name/**location** of a file folder

<p class="note">`file == path & folder == directory`</p>

## FutuRe you

+ Using scripts and writing clear code will make your life easier
+ It's like writing down a routine of pointing and clicking that you don't have to memorize
+ The internet is full of routines/scripts that you can edit and customize to your liking
+ With some notes and some extra attention paid to make sure things are clear, future you will be very happy with current you!
